Aleph returns an error whenever a Snowflake query returns no row.
Aleph currently executes a unload of the query and read the first 100 rows from the unloaded files in s3. Since Snowflake does not create a file when result file is empty, Aleph generates the error when it tries to read from the file.
Check number of rows unloaded. If zero, create an "empty" file (file header row only) from aleph.
